This is entirely dependent on which activities you choose to monitor, the amount of activity generated by the target phone user, and your delivery settings. If you are only using FlexiSPY for live listening via SpyCall and Intercept Call, these features do not use any Internet data at all.
FlexiSPY itself uses no bandwidth as it runs quietly in the background, waiting only to capture the activity you’re monitoring. Most text based logs such as call logs, chats, browser urls, etc use little data to be uploaded into your account. But if for example you’re also capturing lots of pictures, video clips or audio, this type of media can amount to much more data for a very active user.
If you are capturing Locations, depending on the phone’s location settings this may also use the Internet to query GPS satellites. If you choose to capture location very frequently and GPS satellites are used, this may also add up in data use.
Fortunately FlexiSPY is also flexible in how you may use it. You can selectively choose just those activities you want to monitor, and turn off capturing for things you don’t really need. You can capture GPS locations more frequently or less frequently, and change any of these settings at any time.
A report timer determines when to make an Internet connection to upload your data, and this is also fully configurable. It can report in real time or by a schedule you choose. Less frequent reporting means less Internet connections. Additionally, FlexiSPY may also use Wi-Fi access to upload the data. Even better, you may configure the report timer to use Wi-Fi only. For example if the phone is connected to a Wi-Fi network at home, work or school every day, you may not need to use any data from the mobile carrier plan at all.
The bottom line is that FlexiSPY uses only as much Internet as necessary to report the data you’ve chosen to capture. If the target user has 400 megabytes of pictures, audio and video clips that you’re capturing, it will take just that much data to report this media.
But FlexiSPY is also fully configurable as to how often the Internet is used, which apps and activities are tracked, and if it should use 3G, Wi-Fi only or both.
